mjo@gentoo.org This software implements various state-of-the-art algorithms for algorithmic learning of XML Schema definitions and Document Type Definitions. Given a set or a single XML instance it can algorithmically infer a schema which describes the XML instances. The resulting schemas are of high-quality and human readable. The theory behind the project is described in Kore Nordmann's thesis, "Algorithmic learning of XML Schema definitions from XML data," available at http://kore-nordmann.de/talks/11_03_learning_xml_schema_definitions_from_xml_data.pdf.
